71 all whom it may concern:

Be. it known that l, Enwimn M. Unve- MAN, a citizen of the United States, and a resident of Jancsville, county of Rock, and State of Wisconsin, havc ii'ivented certain new and useful Improvements in Cultivators, of which the billowing is a speciiication.

The invention relates to wheel cultivators, and seeks to provide a simple and eilective shii't mechanism for moving'thc l'rame relatively to the wheels and at the same time raising and lowering; the shovel beams, so that-the riders weight will properly balance the machine both when the shovel beams are raised and when they are in working position, and so that the forward pul i oi the team may be utilized for raising the sl ovel beams.

Further objects oi the invention are to pro vide simple and effective means for yicldingly holding the shovel beams in working position and for effecting the adjustment and raising and lowering; of the shovel beams in dependently oi the shift mechanism.

The invention also seeks to provide an improved form of li't't. spring for assisting in shifting: the 't'rafme and raising the shovel beams, together with means for compensat ing for the decrease in leverage of the spring as the shovel beams approach their working position.

The invention consists in the con'ibinations and arrzingements of parts hereinafter set forth, illustrated in the accompanying drawings and more particularly pointed out in the. appended claims.

Figure 1 is a plan view ol' the improved cultivator. Fig. 2 is a longitudinal section thereof with the shovel beams in working position. Fig. 3 is a view similar to Fig. 2 with the shovel beams in raised position. Fig. 4 is an enlarged detail section on lines 4-- i of Fig. 1 showing; the parts of the shift mechanism. l i e 5 is an enlarged detail section on lines 5 5 oi Fig, 3. Fig. 6 is an enlarged detail section on-lines (3*6 01' Fig. 3, and Fig. 7 is a section taken on line 7-? of Fig. 3.

The cultivator is of the wheeled, straddlerow type. The s11 )porting wheels 10 are mounted upon spindles at the lower ends of the arched axlcp This axle (see Fig. 1) prefcrably comprises a central tubular sectionll and dc ending wheel sections 12. The central tu )ular section 11 is rci'erably secured by brackets 13 and U-bo ts 14 to the side tubular section 11 to adapt the machine for diilcrent widths 01 rows.

The forward converging ends of the side bars 15 of the. frame are secured to the pole 17. A transverse brace-bar 18 extends between the forward ends of the side-bars and is connected to the rear end of the pole. A doublctrce 1t) pivoted to the pole is provided at its ends with swingletrces 20. A support ing arch 21 for the forward ends ol the shovel beams is secured to the pole 17 and is connected thereto by the inclined braeebars 22.,

From the arched axle, the side-bars 15 0X- tcnd rearwardly and support the transverse seat-bar 23. This bar is provided with the riders seat 2 1 and with a series of holes 25 in each end for adjustably eneagin; pins 26 on the rear ends of the side-bars 15. Inclined l'nace-bars 27 are secured to the sidc-bars 15 of the frame and extend forwardly and inwardly therefrom and embrace the central; tubular section of the arched axle.

The shovel beams or gangs may be of any usual or suitable construction. lin the form shown, they are constructed of separate secti us 28 bolted together in oitset relation to carry the shovels 2.) on the shanks 30 in proper position. At their forward ends, the sections 28 of the shovel beams are. secured to upright standards 31 that are cohnccted by suitable couplings to the spindles 32 of the arched bar 31. These couplings comprise horizontal sleeves 33 rotatably mounted on the spindles 32 and vertical sleeves 34 adjustably clamped to the horizontal sleeves 33. The clamp for adjustably securing the sleeves 34 upon the rotatable horizontal sleeves 33, comprises an upper member 341 formed .in iece with the sleeves 34 and a lower memlier 342 connected to the sleeves 34 by a bolt 35. The clamp-members 3-11 and 342 are suitably shaped to engage the sleeve 33 and areheld in place thereon by a shovel beams.

bolt 343 that extends through the ends of the clamp members. The standards 31 of the shovel beams or gangs extend within and are swiveled to the sleeves 34. They are secured in place therein by a clamp ring 361.

which fits within'the enlarged central portion of the sleeves 34 and a clamp bolt 36.

The clamp bolt 36 extends outwardly through aslot in the sleeves 34 so that the standards 31 may move within the sleeves to ermit the lateral movement of the shovel beams or gangs. The rotation of. the horiaontalsleeve's 33 upon the spindles 32 per- Inits' the vertical movementof the gangs or shovel beams to and from working position. By loosening the nuts on the bolts 343 the couplings may be shifted'late'rally uponthe sleeves to hold the shovel beams or gangs at different distances a art.

The rear ends of t e shovel beams are upheld by a pair of pivotedsupporting arms 37 that are-connected to the beams by the suspension rods or links 38. Each rod 38 is provided at its upper end with an eye 39 engaging a hook 40 on the upper end of the companion supporting arm 37 and, at its lower end, rod 33 is secured to its shovel beam by a suitable coupling 41.

The supporting arms 37 are pre erably pivoted or 'ournaled directly upon the horizontal, tubu ar section 11 of the arched axle and are held in place on the ends thereof between the brackets 13 and the brace-bars 27.

A balancing shift mechanism is provided for moving the frame relatively to the wheels and at the same time raising and lowering the This mechanism is controlled by a balancing shift lever 42 that is connected by a rock-shaft and a number of links to the depending wheel sections 12 of the arched axle and to the supporting arms 37 of the shovel beams to raise and lower the latter and at the same time shift the frame relatively to the supporting wheels 1.0. The transverse rock-shaft 43 of the shift mechanism is arranged preferably at the front of the machine just below the side-bars 15 and is journaled at its en'ds inbrackets 44 and 45 that are fixed -respectively to'the side-bars 15. The balancing shift lever 42 is secured to the right-hand endof the rock-shaftA-S A outside of the bracket 44.and extends rearwardly within easy reach of the riders seat. A spring-held dog 46 on the forward end of the 'shift-lever 42 is arranged to engage one'of a pair of notches in a sector 47 that is formed on the bracket 44 to hold the shift lever in its raised or lowered positions. Dog 46 is connected as usual by-a rod 48 to an operating hand piece 49 pivoted at the free'end of the lover. The sector 47 is also provided at its ends with steps 50 for positively limiting the throw of the balancing shift-lever 42. A pair of roek arms 51 are fixed to the ends of the shaft 43 outside of the brackets 44 and 45 and extend downwardly therefrom. The right-hand arm 51 is preferably formed in piece with a casting 52 which is clamped to the rock-shaft 43 andwhich forms the forward end of the shift-lever 42. The arms 51 are connected by links 53 to the depending wheel sections 12 of the arched axle. These links are connected at their forward ends to the rock-arm 51 by pivot bolts 54and at their rear ends by pivot bolts 55 to brackets 56 which are secured to the lower ends of the depending wheel sections 12 by U-bolts 57. The opposite ends of these links are preferably provided with two or more holes for the pivot bolts 54 and 55 so that the links maybe adjustably connected to the arms 51 and to the wheel sections 12 of the arched axle. By

the shift mechanism described, the frame of i the machine is shifted relatively to the sup porting wheels as shown in Figs. 2 and 3 to properly balance the machine both in the working and riding positions of the shovel beams.

The rock-shaft 43 isalso provided with a pair of arms 53. which are clamped to the shaft just inside the brackets 44 and 45 and which extenddownwardly therefrom. These arms are connected by links 59110 the sup porting arms 37 for the shovel beams so that the latter are raised and lowered by the balancing shift mechanism. To permit the adjustment of the shovel beams independently of the shift mechanism, the links 59 are connected thereto through. the medium of a'pair of pivoted sector. arms 60.' These sector arms, like the supporting arms 37, are prefwith a s rin ressed do (ii-which en a es one of a series of notches in the upper end of the sector arm to adjustably connect the supporting arm thereto. Dog Glis connected as usual by a rod 62 to an operating fingerpiece-63 pivoted at the upper end of the supporting arm or lever 37.

A portion ofeach sector arm 60 extends below the central section 11 of the axle and is connected to the corresponding link 59 by a pivot pin or bolt 64. Each link 59 is formed of two, slidably and pivotally connected sections 59 and 59 The rear section 59 that is connected to the sector arms 60 is prefer-' ably in the form of a sleeve within which the forward link section 59 slides. A cross-pin.

65 in the rear end of the link section 59 can I 7 tion, so that the two parts ofthe links may be deflected or moved out of line as herein/after described. The connection between the link sections 59" and 59 is what may be termed a slidahle, articulating, pin-andslot upper horizontal section of the archedaxlo in front of the spindles of the supporting wheels and will not begin to lift the shovel beams until the rear ends of the link sections 59 reach ahntments or walls 72 at the rear ends of the link sections 59*. At this point, inas much the fulcrum of the frame has been thrown in front of the wheel spindles, the riders weight and. the draft of the tcain will be exerted to automatically lift the shovel beams. i

The link section or sleeve 59' is formed of two parts connected. by rivets 67. One of these rivets extends through the lower end of projection 68 depending from the forward end of the link section. 59" and forms a pivot for an Lshapcd dog 69. The upper arm of this dog is provided with a head 70 (sec l*ig*.,5 f, whiclnis of sufficient width to en age the lower edges of the link sections 59 and 59 The cog 69 is arranged between. the parts of the link section 59. The sector arm 60 is secured between the parts of the link section 59* by thc pivot pin 64 and extend slightly below the frame as shown. A. coiled spring is connected at one end to the lower end of the sector arm 60 and its other end 'adjustably engages one of the of holes 73 in the lower arm of the dog 69. A stop lug 74 is formed between the parts of the link section 59 and engages the portion of the sector arm 60 below the pivot pin 6st to limit the ing moveii'ient of the sector arn'rand of the supporting arm 37 This step device thus serves to, limit the lowering movement of the supporting arm for the sl'iovel beam so that the latter is upheld in its normal working position. The supporting arm 37, however, may be adjusted relatively to thesector arm 60 and stop device 74 to vary the normal working -position of the shovel beam by tripping the dog 61 and adjusting the supporting arm 37 as desired. I l he engaged with one of the notches of the sector arm to hold the supporting arm 37 in ad- 'justcd position. The sector arm is provided -with laterally pro ecting stop-lugs 75 (see Fig. 7) wl'rich are arrangeih to engage projecting flanges the support ing backward movement of the latter relatively to the sector arm.

()ne of the functions of the spring 71 is to hold the sector arm. 60 and link section 59" in position with the lower end of the sector backward or lower-- for the shovel bcamf dog 61 will then be re- 76 on the front inner end of arm 37 to POSIflYGlY limit the interferes w'th inc arm against the stop lug 74 when the supporting arm 37 is disengaged from the sector arm by tripping the dog 6] this spring the sector arm would be free to move about when the supporting arm 37 was disengaged therefrom. Another function of the-spring 71 is to hold the link sections 59 and 59" yieldingl c in line, but permitting the deflection or articulation of the same so that the shovel beams may be depressed below their working position without disturbing the adjustment, either of the balancing shift lever 42 or of the suppt-irting arms or levers 37. For this purpose, the shovel beams are provided with stirrups or footpieces 77 by which the rider maypropcrly guide the shovel beams in lateral direction. lie may also depress the shovel beams to properly cultivate a low place in the ground. This depression will shift the supporting arm 37 from the position shown in full lines in Fig. 4 to that shown in dotted lines and will also cause a deflection or articulation of the pivotally connected link sections 59' and 59" as indicated in dotted lines in Fig. 4. The deflection of the link sections will stretch the spring 71 through the medium of the dog 69 and, whcn'the pressure of the' riders feet upon the shovel beams is released, the spring 71 and dog 69 will restore the link sections and other parts to normal working position.

By connecting the spring 71 both-to the dog 69 and to the lower end of the. sector arm 60 it not only serves to yicldingly hold the shovel beams in. working position but also, as abovi stated, serves to hold the sector arm in position when the supporting arm S37 is disengaged therefrom. If otherwise arranged, two springs would be necessary to perform these two separate functions An improved arrangement of lift spring is provided. for aiding the operator and the team in balancing the'machine and in raising and lowering the shovel beams. In culti ators of this type it is usual to connect the lift springs to the upper ends of the supporting arms 37. But the movement of the up per ends of the supporting arms, and the necessary stretch of the springs when so connoeted, are so great that only light springs may be employed[ ljlcavy lift springs may be connected to the lower-ends of thcsupporting arms adjacent theirpivots hut,"v.'hcn so arranged, the springs approarh a dead center position when the cultivator beams are lowcred. This decrease in leverage of the prings berorm' i greater as the supporting arms 37 :n'c adjusted, as shown in Fig. 4, to hold the cultivator beams at a low level and prope action of the springs in starting the shovel beams from working position. i

l n accordance with the present invention, heavy lift springs 78 are employed and are Were it not for the rear end of connected at their forward ends by adjusting screws 79 to lugs 80 on the brackets 44 and 45. At their rear ends, the springs are con.- nected by links 81 to thelower ends of the supporting arms 37 adjacent their pivots. These links are in the form of U-shaped stirrups which embrace the lower ends of the arms 37 and are connected thereto by pivot bolts 82. The arms 37 are provided with projections or lugs engage the links 81 and elevate the rear ends of the spring 78 as the shovel beams approach their working position (see Fig. 4). This compensating device is particularly effective when the supporting arms are low working position. The pivot 82 for the link 81 and the lu s 83 for lifting the link and the spring are relatively so arranged as to increase the leverage of the sprin 78 to practically the same extent as such Ieverage is decreased by the movement of the arm 37 toward a horizontal position so that the pull of the spring is effective for starting the beams and shovels from the ground and is substantially the *same whatever may be the adjustment of the supporting arms 37 and shovel beams upheld there by. This arrangement also permits of the use of a heavy lift spring in a self-balancing cultivator of the type described; that is, one in which the frame is shifted to balance the machine at the same time that the shovel beams are raised and'lowered.

' i The invention provides an efficient cultivator having a balancing shift mechanism, which is controlled by a single lever, and by which the weight of the machine is properly balanced as the shovel beams are raised and lowered and by which the rider's weight and r the draft of the team are utilized in raising the same time, the working level of the shovel shovel beams from working-position; At the beams may be adjusted independently of the balancing shift mechanism and the beams are yicldingly supported in working position so that they may be depressed. to cultivate a low portion of ground, without disturbing the adjustment of the balancing lever or of the adjusting levers. The improved arrangement of the lift spring permits of the 1 use of a heavyjspri.ng and. provides means for I holding the springs away from a (lcadcontcr position so that it is effective in all adjustments of the shovel beams. While the stoplugs 7 4 and 7 5 limit the backward movement of thc supporting arms or levels S'Trclativ'ely to the sector arms 60, these arms orlevers may be moved to their extreme forward position independently ofthe sector arms. So that, when the balancing shift'lover is in its lower position, shown in Fig. 2, the arms or-levers 37 may be used to raise and lower the shovel beams independently of the balancing shift mechanism and independently of each other.

83 which are arranged to.

adjusted as I shown n Fig. 4 to hold the shovel beams at a pension. rods 38 are brought well toward the rear of the machine where they may be readily manipulated by the operator in the seat 24.

It is obvious that numerous changes could be made in the details set forth without departure from the essentials of the invention.
